000019873 520__ $$2eng$$aA hysteresis model for seismic response analysis called “deformation history integral type model (DHI model) has been proposed for reproducing hysteresis of high damping rubber bearing by some of the authors. But formula of this model was complex and required many parameters. Therefore the model has been improved for simplicity. The improved model is very simple because only 3 parameters are required in the model. Furthermore no switching condition in the algorism, so the calculation can be executed straightforward. But this model well describes the hysteresis characteristics of horizontal deformation of isolators including natural rubber bearings (NR), high damping rubber bearings (HRB), and so on. In this paper, we show applicability of the DHI model for high damping rubber bearing of various sizes. This model well describes the experimental behavior of isolators including two-directional loading as well as one-directional loading at the wide range of shear strain. This model can well reproduce the horizontal restoring force for random loading including two-directional loading as well. In addition, we show flexibility of DHI model by applying various types of high damping rubber bearings.
